If you don't know what OCD stands for it is Obsessive Compulsive Disorder. Wikipedia defines OCD as "Obsessive-compulsive disorder (OCD) is an anxiety disorder characterized by intrusive thoughts that produce uneasiness, apprehension, fear, or worry; by repetitive behaviors aimed at reducing the associated anxiety; or by a combination of such obsessions and compulsions. Symptoms of the disorder include excessive washing or cleaning; repeated checking; extreme hoarding; preoccupation with sexual, violent or religious thoughts; relationship-related obsessions; aversion to particular numbers; and nervous rituals, such as opening and closing a door a certain number of times before entering or leaving a room. These symptoms can be alienating and time-consuming, and often cause severe emotional and financial distress. The acts of those who have OCD may appear paranoid and potentially psychotic. However, OCD sufferers generally recognize their obsessions and compulsions as irrational, and may become further distressed by this realization." And a tic is described as "A tic is a sudden, repetitive, nonrhythmic motor movement or vocalization involving discrete muscle groups. Tics can be invisible to the observer, such as abdominal tensing or toe crunching. Common motor and phonic tics are, respectively, eye blinking and throat clearing"
With that background definition, if it is new to you than you can have a new realization to how amazing it is that he was able to stop washing his hands after touching her, and how he is now able to leave the door unlocked, and leaves the light on hoping for her to come back. It just breaks your heart. On one hand I can imagine how difficult dating someone with these behaviors would be, IT would require an insane amount of patience and time. Obviously the novelty wore off for this woman, and I hope that he can find someone worthy of him that can give the patience and time that he deserves. Either way his heart break breaks my heart with it's pain.
